Re: [Gm2] RealConv.mod first cut

Hi Gaius,

Unfortunately, these changes break the build on Mac OS X (at least  
10.5/Intel):

gcc   -g -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes - 
Wmissing-prototypes     -DHAVE_CONFIG_H  -o stage1/gm2/cc1gm2 gm2/ 
gccgm2.o gm2/gm2builtins.o gm2/gm2-lang.o gm2/gm2except.o gm2/stor- 
layout.o gm2/m2pp.o gm2/gm2-compiler-boot/gm2.a gm2/gm2-libs-boot/ 
libgm2.a gm2/p2c/p2c-src/src/libp2c.a                     \
                             gm2/gm2-compiler-boot/m2flex.o main.o   
libbackend.a ../libcpp/libcpp.a ../libcpp/libcpp.a -lintl -liconv ../ 
libiberty/libiberty.a -lm

I couldn't find any reference to any flavor of exp10() in the 7  
September 2007 draft of C99 and I don't recall seeing it in earlier C  
standards.  Perhaps pow() is needed instead.
